Resumen del Recurso
The Life Cycle of a star
Protostar
Main sequence star
Red SUPER giant
Supernova
Neutron Star
EXPLODING supernova THROWS OUTER LAYERS OF DUST + GAS into space
VERY DENSE CORE IS LEFT
Black Hole
If the star is big enough, IT WILL THEN BECOME A BLACK HOLE
The above EXPLODES to form a supernova
Elements HEAVIER THAN IRON are made
They are ejected into the universe to form new stars/ planets
Stars BIGGER than our sun
It's red because THE SURFACE COOLS
UNDERGOES MORE FUSION, STAR EXPANDS AND CONTRACTS MANY TIMES
STARTS TO GLOW BRIGHTLY AGAIN
Elements AS HEAVY as iron are formed
Red giant
The fuel for the main sequence star (HYDROGEN) RUNS OUT
Elements SUCH AS IRON are made by NUCLEAR FUSION OF HELIUM
Planetary Nebula
White Dwarf
The left over is a dense, solid core
Black Dwarf
The WHITE DWARF COOLS
This will eventually DISAPPEAR
Red giant BECOMES UNSTABLE and EJECTS OUTER LAYER
GRAVITATIONAL ENERGY BECOMES HEAT ENERGY
THIS CAUSES TEMPERATURE RISE
HYDROGEN undergo NUCLEAR FUSION to form HELIUM
They give out HEAT and LIGHT
The star enters stable period, GRAVITATIONAL FORCES = OUTWARD PRESSURE
THE STAR CAN STAY LIKE THIS FOR BILLIONS OF YEARS
Starts as clouds of dust and gas
FORCE OF GRAVITY makes the gas and dust spiral together
